A programmable electronic system (PES) was devised following the guideline ‘Design for Simplicity’ throughout its entire development. Its most essential characteristics are task execution without using interrupts, as well as scheduling in direct reference to Universal Time Co-ordinated. Both the hardware structure and the operating principle stand out due to their inherent simplicity. This leads to a high level of dependability and safety, eases verification, reduces cost for safety licensing, and conforms particularly well with the safety standard IEC 61508.

In case of the 2D cellular automata (CA) the whole rule f can be considered the set of sub-junctions grouped due to the number of "ones" in the neighbourhood. Such decomposition enables indication of sub-functions, which are more important for the global dynamics of the automaton then others. The cellular automata can be implemented on a cellular neural network (CNN). The simplest way of such implementation on the CNN universal machine was proposed by Cronuse and Chua (1995). We present the modification of this method due to which the information about sub-functions can be saved; and from this we are able to simplify the architecture of a CNN-universal machine implementing CA. Furthermore, the shortage of the time of a new state evaluation is possible. The advantage of the modified CA implementation is the possibility to receive the new automaton by manipulation of this part of the structure, which is connected with the sub-function.

Classical, analytical models of queueing systems are used only under the assumptions that mean service times of resPective channels differ between themselves insignificantly. In practice, such a situation hardly ever happens. In this case applications of the classical models cause certain errors. A new class of analytical models with individual characteristics of each service channel is presented. The developed models are described on the example of M / M / m /FIFO/ m + N queueing system. System of equation for two and three channels with individual service is introduced and solved in the paper. The obtained analytical results are generalised onto m service channels.

The real time "blind" correction of dynamic error of instrumentation amplifier has been proposed. It bases on the Pfriem postulate, that the system of two analog channels of different time constants is free of dynamic error when the difference of their output signal always equals zero. An extension of this method has been proposed in this paper. The time constants of the transducer may change independently one from another. For correction of the inertial object dynamic error, the differentiation in real time of the transducer output signal is necessary. This operation is performed by DSP. The multiparametric optimisation algorithm changes coefficients of the corrector in that manner to fulfil the Pfriem postulate. A criteria like /spl par/ /spl par//sub 2/ or /spl par/ /spl par//sub /spl prop// are assumed for the difference between an output corrected signal of each channel. The high order case has also been mentioned.

This paper aims initially to present an identification method for constructing an interval model which can be aggregated to robust control design. Mathematical programming is used as a tool to achieve this goal. We, then, formulate necessary conditions for robust stability of continuous and discrete interval plants and seek low order controller candidates for both cases. Decision making strategies based on Kharitonov and Mansour-Kraus results are proposed to effectively construct and solve standard linear programming problems instead of interval ones. The so obtained candidates are cheked for guaranteed robust stabilizers using (generalized) edge or box theorems
